Central to the tandem mass spectrometry experiment is the process that gives rise to product ions, i.e. the reaction intermediate to stages of mass analysis. Changes in mass or charge of the parent ion (or both) are generally readily detected by all forms of tandem mass spectrometry. Charge changing, or charge permutation, reactions have a long history in mass spectrometry. However, with the advent of new ionization methods, such as electrospray ionization, and the expansion of tandem mass spectrometry instrumentation to include ion trapping instruments, the past decade has seen a major increase in the types of charge permutation reactions that can be studied. Most charge permutation reactions involve electrons or protons as the charge mediating agents. This report, therefore, provides an overview of charge permutation reactions involving protons or electrons. Particular emphasis is placed on processes that involve interactions of precursor ions with gaseous neutral species, electrons or oppositely charged ions. Charge permutation reactions involving electron gain/loss are described first according to a rough order of the energy required for the reaction beginning with the most endoergic reactions and ending with the most exoergic reactions. An analogous approach is then taken with charge permutation reactions involving proton gain/loss. Important charge permutation reactions discussed herein, among others, include those referred to as charge inversion, charge stripping, electron capture dissociation, collision-induced ionization and charge separation. These reaction types, and others described herein, are the subjects of active research and are also finding use in many current areas of application.

The many-channel quantum defect method has been used for the calculation of the photoionization cross section of ground-state nitrogen atoms in the dipole length approximation. The calculations couple three channels corresponding to the 2s 22p 2 and 2s 2p 3 configurations of the residual ion. The results obtained are in agreement with experiment for the energy region between the ionization limit and 1 rydberg unit beyond.

“…As it follows from the general considerations [19], this process has a resonance character and should play an important role at low and intermediate impact energies. Reaction (2) describes the cascade population of the 4p 5 4d5s 2 states due to the radiative transitions from the high-lying autoionising states (see Fig.…”

The ejected electron spectra corresponding to the electron decay of the 4p 5 n1l1n2l2n3l3 low-lying autoionising states in strontium atoms were measured in the impact energy range from the excitation threshold of states up to 200 eV. By using the results of single-configuration Hartree-Fock (HF) calculations, six ejected electron lines with the lowest excitation thresholds were attributed to the decay of the (4p 5 4d5s 2 ) 3 P0,1,2 and 3 F2,3,4 autoionising states. For the 3 P1,2 and 3 F4 states the excitation functions were obtained at an incident electron energy resolution of 0.15 eV. In all excitation functions the strong near-threshold structure was revealed for the first time. The origin of the structure was attributed to the decay of short-lived states from the 4p 5 5s 2 4d 2 configuration of Sr − ion. The cascade population of the 3 P0,1,2 and 3 F2,3,4 states was considered by using the HF energies and decay probabilities for the 4p 5 5s 2 5p levels.
